Cyclopropane carbonyl chloride is an important intermediate.

环丙甲酰氯是一种重要中间体。

Sugar alcohol (alditol) An alcohol derived from a monosaccharide by reduction of its carbonyl group (CO) so that each carbon atom of the sugar has an alcohol group (OH).

单糖羰基(CO)还原得到一．而糖分子每碳原子都连有一羟基(OH)。

And it mainly includes the action of 1,3-diethylene alkylation and acidyl; the action of addition of carbonyl compound; the action of chlorortrimethys:lane and the reaction of diethy lene.

对含硫碳负离子─—1，3-噻烷合成方法及其在有机合成上应用进行比较系统，主要1，3-噻烷烃基化和酰基化反应，与羰基化合物加成反应，与氯化三甲硅反应及1，3-噻烷还原反应。

At the same time, some other oxycompound groups, such as carbonyl group, aldehyde group and ketone group, appear or increase with temperature rising.

与此同时，醛、酮、酯类羰基、芳香酮、醛类羰基等类含氧基团或者从无到有，或者官能团数量不断增加。

This paper andlyses and disscusses the application of group of equal value in syn-thetize to the synthetize of carbonyl chemical compound.

本文并讨论了某些合成用等价基团在合成羰基化合物中应用。
